EMBOSSING MACHINE.

Application filed February 20, 1923. Serial No. 620,271.

To all whbm it may concern:

Be 1t known that I, EDWIN H. REIBER, a citlzenof the United States, anda resident of West Webster, in the county of Monroe and State of NewYork, have invented a new and Improved Embossing Machine, of which'thefollowing is a full, clear, and exact description.

'This invention relates to improvements in embossing machines,and hasparticular referenc'eto a machine for embossing wood slabs or'panelsespecially usedin building bird houses, such as disclosed in my PatentNumber 1,185,345, dated May 30th, 1916.

In the construction of houses such as described in the above patent, ithas been cus tomary to employ sassafras and red cedar, both of whichwoods are of the bark bearing type. It has further been found that theuse of these woods is not essential in constructing the houses and maybe dispensed with in lieu of some other timber having the appearance ofbeing bark bearing.

,An object of the present invention is to provide an improved machinewhich may be utilized to char a slab of wood in suchmanner that thesamewill be given antique grain and wood bark effects suchas in sassafraswood. 7

Another ob ect is the provlsion' of 1mproved means for positioning aslab of wood with respect to the embossingv roller and feeding-the slabthereto whereby the embossing operation is'facilitated. I

A'further object isto feed a slab of wood into direct contact with arotatable embossing elementby the cooperation of said element with othermeans having a relative movement with respect to said element.

A still further object is the provision of a rotatable embossing rollerhaving direct contact with a slab of wood to emboss the same and whichis heated by a flame projected into one end thereof.

The above andother objects will appear vmore clearly from the followingdetail description, when taken in connection with the accompanyingdrawings, whichillustrate a preferred embodiment of the inventive idea.

In the drawings Figure 1 is a front elevation of the .machine, partly insection, and taken on the line 1 1 of Figure 2;

side elevational view taken of Figure 1;

2 Figure 2-is a on the line 2-2 Figure 8 isa section on the line 33 ofFigure 1;

Figure 4 is a section on the line 44 of Figure 1;;and V Figure5 is afragmentary plan view of oneof the slabs showing the result of theembossing operation.

- Referring more particularly to the companyingdrawings, the numeral 10indicates the main frame which includes a pair said screw member beingengaged in the lower portion of the frame 12 so that upon rotation ofthe member 15 a vertical movement in either direction may be imparted tosaid frame 12. Extending laterally or forwardly from' one verticaledgeof the frame 12 is a web 17 having its upper end formed with ahorizontally disposed platform. 18 arranged forwardly and to one side ofthe frame 1 2. A pair of parallel guide strips 19 are mounted upontheplatform 18. These strips are arranged for adjustment toward and awayfrom each other by'the provision of transversely extending slots 20formed in the platform 18 so that vthe strips may be properly adjustedto re ceive therebetween the slab of wood 21, which is first .mountedupon the platform between said strips preparatory to the embossingoperation. In the formation. of these slabs the same are preferablyprovided with a flat surface and a convex surface, as illustrated inFigure 1, but it will be readily understood that said slabs mayhaveother configurations without departing from'the spirit or scope ofthe present invention.

Journaled in the upper portion of the frame 10 and extendingtransversely thereof is a shaft 22 having a pulley 23 at one end thereofby means of which the shaft may be rotated, the opposite end of theshaft projecting beyond the adjacent side of the frame and havingdetachably mounted thereon an embossing roller support 2st including aplurality of arms 25, the free ends of which have fdetachably securedthereto the embossing roller 26. This roller is pr.ovided with an openend and, in the present instance, is shown as having an annular concaveembossing surface 27, although it is to be expressly understood thatthis surface may be convex or flat. It will also be obvious that theroller may have a plurality of adjoining concave or convex embossingsurfaces in the event that it is desired to emboss a slab of relativelygreater width than the one shown in the drawings. Projecting-from oneside of the frame 10 and at the upper end thereof is a horizontallydisposed supporting arm 28 which supports a hanger 29 adjustablelongitudinally of said arm, said hanger in turn supporting a heatingelement 30, preferably in the form of'atorch which is utilized toproject a flame into the open end of the roller 26, whereby toadequately heat the same to accomplish the embossing operation when theslab 21 is brought in contact with the roller 26. The interior surfaceof the roller 26 maybe provided with a lining 31 of any suitable heatretaining Substance which will aid in'maintaining the temperature of theroller constant.

A second shaft 32 is journaled in the upper end of the auxiliary frame12 and has one end projecting from the side of the frame rearwardly ofthe platformlS. A pair of feeding rollers 33 are mounted upon said endof the shaft 32 and adjustable thereon toward and away from each otherso as to properly engage slabs of different widths. The feeding rollersare positioned directly below the embossing roller 26 and havetheirperipheries arranged in the same plane with the supporting surfaceof the platform 18 so that as the slab21 is pushed rearwardly from saidplatform the rollers 33 will engage the under surface thereof and feedthe slab between the same and the embossing surface 27 of the roller 26.From the foregoing description, it will be obvious that the verticaladjustment of the frame 12 is provided for. the purpose of accommodatingvarious thicknesses of slabs between the rollers 26 and 33, thuspermitting engagement of the surfaces of the slabs to be embossed withthe embossing surface 27 regardless of the thickness'of said slabs.

In order to facilitate the feeding of the slabs between the rollers 26and 33, said rollers are driven in opposite directions by means of spurgears 34 and 35 carried,

respectively, by adjacent ends of the shafts centric with said pivot andat all times in engagement with the gear 35. The gear 36 is arrangedadjacent one end of the arm 38 so that when said arm is swung about itspivot 39 the gear 36 may be adjusted toward and away from the gear 3t.The plate 40 is provided with an arcuate slot 41 through which extends apin 12 carried by the arm 38, a wing nut or other fastening device43being threaded upon said pin and engageable with said plate to retainthe arm 38 in various adjusted positions. reason of this construction,it will be obvious that the arm 38 may be adjusted'to disengage the gear36 from the gear 34 to stop the rotation of the shaft '32 and, conse.quently, of the feeding rollers 33 and also that when a verticaladjustment of the frame 12 is made with a consequent movement of thegear 35 toward or away from the gear 3 f, an adjustment of the arm .38may be accomplished to properly intermesh thegears 3a and 36 so that theshaft 32 may be rotated.

' In the operation of the machine, a slab '21 is first placed upon theplatform 18 between the guide strips 19 and then forced real'wardly toengage the under surface thereof with the peripheries of the feedingrollers 33 and the upper surface thereof with the embossing surface 27of the roller 26. The rollers 26 and 33 being driven in oppositedirections will cooperate to withdraw the slab from the platform 18 andthe heat applied to the embossing surface 27 will be transmitted to theupper or convex surface of the slab 21 and char said surface as the sameis passed beneath the roller.

The design of the embossing surface 2 7 may be made to produce antlquegram and bark effects, such as found on Sassafras .wood and after thisdesign has been transferred to the upper surface of the slab the charredwood is brushed off and the raised portions of the surface sanded,leaving the finished product. By charring or burning the surface in themanner herein described ment with said embossing surface, a heatingelement arranged to project a flame into the open end of said roller toheat the same, and

a heat retaining lining for-the interior of said roller. I v
